Lie Algebras In Particle Physics: from Isospin To Unified Theories (Frontiers in Physics)
Howard Georgi
it's here if you want it.
you'll have to work for it.
this is not written by a mathematician, so fellow math phDs be ready.
i didn't make it too far, but i wasn't so beaten down that i might not crack this one open again.
do the world a favor, please: read this book and write a slightly more understandable version of it (with more pictures :) ).
